Technology Wanted:
Wireless Power Transmission to Operate a Large, Moving Part on Heavy Industrial Equipment (Crane).

Status: Completed
Deadline for Submissions: Dec-13-18
Award: $2,500 referral fee for each accepted lead.
An accepted lead is a lead that the client decides to follow up on.

A client is seeking enabling technologies for wireless power transmission to operate a large, moving part in a product line of heavy industrial equipment (crane). The part moves back and forth, from 0.05 meters to 15 meters away from the power source.

Currently, power is supplied via electrical cables which often break or malfunction as the part moves. The available space in the equipment for wireless power reception is 250mm×260mm×500mm. This space is difficult to access and, consequently, a technology that requires routine removal (e.g., for charging) from the equipment will not meet the need.

The client seeks a technology that could be adapted to provide reliable, wireless power transmission. A minimum of 24 volts at 5 amps operating current is needed to operate the crane sensors and controller. Power consumption is approximately 100W, running continuously for at least 5 hours. The client is specifically seeking solutions from companies that can provide consulting services to modify the technology as needed.

Enabling technologies of interest will have the potential to provide wireless power transmission that can:

  1. Power a moving part which moves from 0.05 m to 15m from the power source;
  2. Provide a minimum of 24 volts at 5 amps operating current;
  3. Provide 100 watts of continuous power for a minimum of 5 hours;
  4. Receive the wireless power signal in the 250mm×260mm×500mm space available;
  5. Meet Grade IP67 for dust and water resistance;
  6. Function in an industrial environment with machinery grease, dust, and vibration;
  7. Function within a temperature range of -25o to 80℃; and,
  8. Avoid increasing temperature above 80℃.

Technologies of greatest interest will:

  • Cost less than US$4500 per unit (based on multiple units)
  • Require less than 5 hours for in situ charging (if applicable)
  • Have a working life of more than 2 years with daily use

Technologies not of interest are those that:

  • Consist of a more durable wired electrical cable system
  • Require routine removal of the system or components from the equipment
